Intertronics supplies the 2-K-DOS metering, mixing and dispensing system
Intertronics now supplies the 2-K-DOS metering, mixing and dispensing system, a compact, benchtop system suitable for materials including silicones, polyurethanes and epoxies. The 2-K-DOS is said to provide a clean, efficient and accurate way to apply two-part materials in applications including electronics and LED potting and encapsulation, casting, form-in-place gasketing, sealing and adhesive dots and beads. Its unique modular design provides simple configuration and easy maintenance.
The system accurately meters the components using gear pump technology, which is programmable from a simple control panel. Intertronics asserts that, unlike other gear pump technology, it is conveniently sized for benchtop operation, which can be triggered using a foot pedal or fingertip switch. It can be configured to work with automation to achieve both consistent dispensed amounts and accurate placement.
During operation, material is fed from the two integrated gravity-fed reservoirs through the gear pumps, where it is metered through flexible hoses to a dispensing head. It uses industry standard static mixing nozzles to achieve a homogenous mix, free of air bubbles. The mix ratio, dispensing rate and dispensed quantity can be programmed to provide accurate metering, mixing and dispensing. The system is configurable; the user can vary the mix ratio (from 1:1 to 1:10), shot size (from 2 µg upwards) and dispensing rate (20-1,000 g/min). This gives it some advantage over similar sized systems based on piston pump technology.
“The modular design means each 2-K-DOS machine is built to suit a customer’s process,” explained Kevin Cook, technical manager at Intertronics. “We can adjust features like the reservoir size and dispensing hose length for the application. Our customers can easily retrofit the system to suit their future requirements, for example a change of material, and maintenance requirements are simple, as any part can be easily replaced if needed.
“This compact, easy to use and adaptable machine complements Intertronics’ existing technology range,” added Cook. “It can be combined with either handheld dispensing equipment or Fisnar robots and can meter, mix and dispense many of the materials in our range.”
